"Chika probably hasn't noticed. Don't let anything slip once you get home."
The party was coming to an end. After Rin Ito dressed, he pulled Moeha into the living room. Inside the bedroom, Kaguya and Ai were still mercilessly "bullying" Chika's breasts. They had known Chika since middle school and watched her grow while they remained stagnant. They feared their friend being flat, but they feared her being well-endowed even more—especially when they remained small themselves!
They were finally letting out years of repressed jealousy.
Moeha wanted to join them, but Rin had called her out. Her face still had faint white stains—it was hard to tell if it was milk or something else. Combined with her innocent smile, it gave Rin a forbidden sense of pleasure, like corrupting something pure.
"Hehe, don't worry, Big Brother~ I won't say a word~" Moeha nodded cheerfully.
Today's party had fully satisfied her expectations. While it wasn't quite a "basement training" scenario, seeing her sister's first time and seeing the cold Kaguya-san begging for mercy was enough.
Although it was Chika's first time, Kaguya was actually the one who took up most of Rin's attention. As for Kaede... she didn't actually join in the sex. To maintain her authority, she couldn't show her "real" skills, or people would realize she was just as depraved. She stayed in her role as the "observer" and assistant, much like Moeha.
Moeha had been obsessed with pushing. Whether Rin was with Chika, Kaguya, Ai, or Rin Hoshizuki, she was always behind him, giving him an extra push.
"Alright, it's late. We're finishing up here. I have to take Chika to the hospital for a checkup, so you should head home first."
"Okay~ Oh, I don't have Big Brother's contact info yet." Moeha pulled out her phone and showed him her QR code.
Moeha: [(*?▽｀)ノノ]
After adding him, she sent a cute emoji immediately. She put her hands behind her back and smiled into Rin's eyes. "Can I come find you to play sometime?"
"Find me to play?" Rin sized her up. Play what? Play with you? He wondered if this "Pink-Black" sister was going to say, "Big Brother, you wouldn't want my parents to find out about this party, would you?"
"Yeah~ I'm quite interested in you, Big Brother."
Moeha had known Kaguya for years and was a total fangirl. Most boys were just boring classmates to her. What kind of man could make the Ice Queen Kaguya fall in love so quickly? Surely it wasn't just because he was big and good in bed? There had to be more.
"Sure. Just let me know when you want to come over."
"Eh... no surprise visits? Are you trying to hide all your weird stuff beforehand?"
"Nothing to hide. I just won't be around in a few days."
Summer break had a week left. Eriri and the others were still on the island, and he needed to check their progress. The script was done, Utaha and the Fairy were writing their new works, and Eriri could finish the CGs quickly once she had the script. The main hurdle was Megumi Kato's programming.
"Okay~ I'll call first. But..." Moeha winked mischievously. "Keep it a secret from my sister and Kaguya-san~"
After making sure Moeha washed her face and straightened her clothes in the bathroom, Rin sent her off. He returned to the room to find Chika's breasts covered in faint bite marks. Kaguya and Ai were still nibbling on them as if trying to suck the volume into their own bodies.
Smack!
Rin swatted both of their asses to make them stop, then finally removed Chika's blindfold.
"Ugh..." The bright light made Chika cover her eyes. Once she adjusted, she looked resentfully at the traces of milk on the corners of Kaguya's and Ai's mouths.
"Kaguya and Ai are both... perverts! I never knew you guys loved sucking so much!"
"Who told you to have such slutty tits? Tits this lewd were born to be handled."
"Perverts!" Chika muttered, pulling the duvet over her legs and clutching a pillow to hide her messy state. She looked at Kaede. "Kaede... you saw it clearly, right?"
"Yeah, yeah, I saw."
Chika sighed in relief, then spoke tentatively. "Then... when should I take him to meet my parents?"
Since she was "pregnant," she couldn't hide it forever. She needed to discuss whether to keep it or not with her father.
"That's fine, but... are you really pregnant?"
"How could I have so much milk if I wasn't?!" Chika sniffled. The room still smelled faintly of it.
"No, no. I've seen girls lactate without being pregnant... Karen is like that. You should really go to a hospital and check first," Kaede said seriously.
"Huh?" Chika froze. She knew Karen Onjouji from social circles. "Wait... this is the Onjouji family hotel, isn't it?"
Chika had a sudden, wild thought. Does Karen have this kind of relationship with him too? Did she do these lewd things on this very bed?
"If you don't believe me, call her and ask. That's why I told you to go to a doctor first." Kaede looked away guiltily. The "lactation" was only happening because she had used the System to "enhance" them.
"Eh? EEEHHHHH!?!?!" Chika wailed, clutching her pillow. She didn't know which was worse: being pregnant or not. "If I'm not pregnant... didn't I just give myself away for free today?!"
